Well since projection can NOT work good in daylight, you kind of ended it for yourself right there.skaman74 said:
To answer in more detail: Will you see a picture on your screen in daylight? Well, yes you can. And depending on how bright the projector is (HD20 isn't that bright) you might even be able to see what's going on. But the picture will look so washed out, it's nothing I would bother to look at.
In order to watch ANY kind of projection system, you have to have strict light control. The darker the better. Pitch black with no reflections in the room would have the best looking results.
